| الوصف: | The NW coast of the Iberian Peninsula is dominated by extensive shellfish farming, which places this region as a world leader in mussel production. Harmful algal blooms in the area frequent lead to lengthy harvesting closures threatening food security. This study developed a framework for the detection of Pseudo-nitzschia blooms in the Galician rias from satellite data (MERIS full-resolution images) and identified key variables that affect their abundance and toxicity. Two events of toxin-containing Pseudo-nitzschia were detected (up to 2.5 μg L −1 pDA) in the area. This study suggests that even moderate densities of Pseudo-nitzschia in this area might indicate high toxin content. Empirical models for particulate domoic acid (pDA) were developed based on MERIS FR data. The resulting remote-sensing model, including MERIS bands centered around 510, 560, and 620 nm explain 73% of the pDA variance (R 2 = 0.73, p < 0.001). The results show that higher salinity values and lower Si(OH) 4 /N ratios favour higher Pseudo-nitzschia spp. abundances. High pDA values seem to be associated with relatively high PO 4 3 , low NO 3 − concentrations, and low Si(OH) 4 /N. While MERIS FR data and regionally specific algorithms can be useful for detecting Pseudo-nitzschia blooms, nutrient relationships are crucial for predicting the toxicity of these blooms ; This study was funded by the European Commission's Marie Sklodowska-Curie Action (project 20501 ECOsystem approach to Sustainable Management of the Marine Environment and its living Resources (ECOSUMMER)). |
